S ?. Mid- and bindtibia wbite above ; the latter in (J as long as, iu ? 2 mm. 

 longer tban, tbe first tarsal segment ; sjiurs very nneqnal, sbovt ones less than 

 half the lengih of tlie long ones, these not quite half the length of the first tarsal 

 segment. Forewing below with black streak behind the cell, hinder margin in S 

 abont as long as, in ? 4 to 6 mm. longer than, distal margin : the pale costal area 

 on the forewing above distinct. 



(?. Tenth abdomiual tergite (PI. XXIII. f. 24) very different from that ut 

 all the other species, its apical half being very strongly narrowed with the apex 

 i/of sinnate ; the underside of this narrow portion is strongly chitinised, having 

 the apjiearance as if the sides of the tergite, instead of being spread out laterad, 

 were lent downwards and had become fused together in the mesial line ; the tip 

 of the tergite is curved ventrad (PI. XXIII. f. 28), forming a hook which is 

 vertically thicker (side-view) than iu the allied species, owing to the under surface 

 slanting from each side towards the raised mesial line (r) ; sternite also very 

 remarkuble, being produced into two long processes (PI. XXIII. f. 24). The harpe 

 (PI. XXXII. f. 11) consists of a ventral triangular ridge /j 6', which is subvertical 

 upon tlie jilane of the clasper and covered for the greater part with small scales; 

 the suhmesial ridge cm is basally produced into a compressed ])rocess.^i, while it 

 fades awiiy distally into the vermiculur folding of the clasper; the dorso-bsisal process 

 j)M is slender, curved, ajiically dilated and here beset with bristle-bearing tubercles. 



? . The eighth tergite very diflerent from that of the other species in being 

 deejily divided by a narrow sinus (PI. XVI. f. 5. 6), the two lobes more or less 

 notched or irregularly emarginate. The vaginal plate also characteristic (PI. XVI. 

 f. 4. 5) : the vaginal orifice (c) mesial, surrounded proximally and laterally by a 

 fold, at each side of the orifice there is a groove bordered by a fold ; the postvaginal 

 plate very broadly rounded, almost truncate, extremely feebly emarginate mesially ; 

 fig. 5 gives a side-view of the end of the abdomen, showing tbe relative position 

 of tbe dorsal and ventral plates ; tbe anal cone (consisting of segments ix. and x.j 

 is somewhat pushed anad to make it visible.
